I've recently watched a Japanese animated historical drama, The wind rises, based on the biography of Jiro Horikoshi, designer of the Mitsubishi A5M fighter aircraft, which was widely used in World War II.

Having been universally acclaimed and awarded quite a few prizes this animated film is clearly thought provoking, as it goes way beyond the biopic it is meant to focus on.
Hayao Miyazaki who wrote the script based on a 1939 short novel by Hori Tatsuo and directed the film is known as often being "preocupied with absence, the value of things left behind and how ghosts of beautiful things are traced onto our memories" and I believe he managed to capture and put all of that in this biography oriented film, which otherwise might have been deprived of its beauty.

"Mr. Miyazaki renders Jiro's life and dreams with lyrical elegance and aching poignancy" - Nicolas Rapold - New York Times
